Citrix App Won't Launch

Hi All,

I really need some help with regards to a Citrix App. We recently launched a new app to a department, and although neraly everyone was able to get in - we had about 6 people for whom it wouldn't launch.

Basically what was happening was the initial app would launch (bit like the Windows control panel), but whenever they clicked on an icon within the Window, nothing would happen. Going into the PNAgent Connection Center, you can see the server you're connected to, but it only shows the window open that you have on your screen. When you select 'Logoff', you get a program not responding message. You can then see the requested App had launched, it was just not showing on the client machine (running in the background somewhere).

Various people have looked into this for months, but not been able to resolve the issue.

Initally, we found that deleting the user's local profile on the machine allowed them to run the app successfully - but 24 hours later the probelm would come back. Our final 'Quick Fix' was to swap their current desktop machine with that of another user. This, for some reason, fixed the problem. Now this has worked for everyone - bar 1. I've now been told that we should try deleteing their AD account and re-creating it, but it's going to cause so much mess; I want to try and avoid it.

I need to know if anyone knows anything I can try to get this App to launch. Like I say, it appears to be user related and not a server probelm as everyone else can seem to get into it. There's no permission problems as the client can use the app for the first 24 hours (if I was to delete their profile on the machine), but then nothing.. Is there something in the registry that affects a Citrix app? What could be causing the problems locally - It's just a normal XP SP2 machine with Office 2003.

You are my last and only hope!

Many Thanks,

Pete
